SPECIFICATION forming part of Letters Patent No. 661,276, dated November 6, 1900.

Application filed October 12, 1899. Serial No. 733,361. lNo model.)

To all whom it may concern:

Be it known that I, GUSTAF L. REnNsTIERNA, a citizen of the United States, residingat Winchester, in the county ofMiddleseX, State of Massachusetts, have invented a certain new and useful Improvementin Mufflers and Purifiers for Gasolene-Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

In the use of gasolene-engines there is a constant escape of refuse gases through the exhaustpipe, which if discharged directly into the open air give off offensive odors and also usually produce a hissing sound.

The object of my invention is to provide an attachment to the engine whereby the refuse gases will be cleansed and freed from offensive odors before escaping into the open air and whereby also the sound of the escaping gases will be muflled.

My invention will now be fully described, and the novel features thereof will be particularly pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a vertical section, on line 1 1 of Fig. 2, of an apparatus embodying my invention. Fig. 2 is a horizontal section on line 2 2 of Fig. 1.

The bulb or chamber 1 is formed with a mouth 2, by which the bulb may be connected with the exhaust-pipe of a gasolene-engine and through which the refuse gases are conducted into the bulb. Surrounding the bulb 1 is a vessel or shell 3, which is secured to the bulb in an y suitable manner, as by the rods or stays 4, which may be bolted or otherwise securely fastened to the bulb and the shell, the neck of the bulb extending, preferably, above the shell, as shown. The shell 3 is closed at the bottom and sides and is of sufficient size to form a hollow space below and around the sides of the bulb 1. The upper end of the shell 3 is formed with an inwardly-turned flange 5, which does not extend quite to the bulb 1, but leaves an annular passage 6, leading from the interior of the shell to the outer air. A tubular conduit for the gases leads from the interior of the bulb, through the bottom or sides thereof, into the lower part of the vessel 3. Preferably this conduit con sists of a plurality of tubes 7 open at both ends, which pass through the bottom of the bulb 1 and are suitably secured in position by soldering or otherwise, so as to form a plurality of small passages from the interior of the bulb to the lower part of the shell 3, the tubes preferably extending some distance below the bottom of the bulb and radiating outwardly from each other at their lower ends, so as to more widely distribute the gases when they pass from the bulb into the shell. The shell 3 is partially filled with water up to some point above the lower ends of the tubes 7, the level 8 of the water being lower than the upper ends of the tubes. The gases from the exhaust-pipe will pass into the bulb l, thence through the tubes 7 and the Water therein into the water in the shell. In passing through the water the gases will become decomposed or be freed wholly or in large part from their impure elements before passing up to the surface of the water, and they will rise quietly instead of making a disturbing sound. After rising to the surface of the water they will pass up through the shell and out through the annular opening 6 into the outside air noiselessly and free or substantially free from noxious or objectionable odors.

One use to which I purpose applying the attachment embodying my invention is to connect it with a gasolene-engine such as is employed for running motor-wagons. In order to prevent the water from splashing over the top of the shell or receiver 3 when the shell or receiver is jolted or shaken, as may occur when the wagon is in motion, 1 secure an annular flange 9 around the bulb uearits upper end below the flange 5 of the said shell 3. This flange is suitably secured to the ex terior of the shell or receiver in any wellknown manner. If desired, the flange 9 may be located lower down on the bulb 1--that is, nearer the level of the water in the receiver 3or more than one such flange may be em ployed, if desired, in which latter case one of said flanges may be located near the top of the bulb 1 and another lower down on said bulb or on the inner face of the wall of the re ceiver. In general, however, one such flange located on the bulb 1 will be found sufficient to prevent the water from splashing out of the shell or receiver 3.

Instead of water I may use in the receiver 3 any liquid having suitable absorbing or decomposing properties for the exhaust-gases.

What I claim is 1. A m uffler and purifier for connection with agasolene-engine,comprisinga bulb into which the exhaust of the engine discharges, a vessel or receiver iuclosing the said bulb and containing a quantity of liquid, a conduit leading from the interior of the bulb into said vessel or receiver and discharging into said liquid, the said vessel or receiver having in its upper part a liquid-retaining flange 0r rim and a narrow or contracted opening adjacent said flange or rim, encircling the bulb, and permitting the passage of the gases, substantially as described.

2. A muflier and purifier for connection with agasolene-engine,comprising a bulb i nto .Which the exhaust of the engine discharges,

a vessel or receiver inclosing the said bulb and containing a quantity of liquid, a plu rality of tubes leading from the interior of the bulb into said vessel or receiver and dischargingfinto said liquid, the said vessel or reor rims at the upper part of said vessel or re-- ceiver having between them a contracted opening encircling the bulb, and permitting the escape of the gases, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
